Plot the bode response for.

bodeplot(Li);

The magnitude plot for all the models varies in the 3-dB range. The phase plot shows the

most variation, approximately 20°, in the [1 10] rad/s interval.

Vary Outer-Loop Controller Gains

For outer-loop analysis, vary the gains of the outer-loop PI controller block, C1. Vary the

proportional gain (Kp1) and integral gain (Ki1) in the 20% range.

Kp1_range = linspace(Kp1*0.8,Kp1*1.2,6);

Ki1_range = linspace(Ki1*0.8,Ki1*1.2,4);
